Calibrator_InterfaceType – OPC UA interfaces for plastics and rubber machinery – Extrusion

6 Calibrator_InterfaceType

6.1 Calibrator_InterfaceType Definition

This OPC UA ObjectType is used for the root Object representing a calibrator as part of an extrusion line. It is based on the ExtrusionDeviceType (defined in OPC 40084-1) and formally defined in Table 1.

The instance(s) of Calibrator_InterfaceType shall be located under the Machines Object of the Server (see OPC UA for Machinery).

NOTE: If the OPC UA server is implemented in the control of the calibrator so only one instance of Calibrator_InterfaceType will be created. But it is also possible that one OPC UA server is connected to several machine controls as one interface to the MES. In this case several instances of Calibrator_InterfaceType will be created.

The BrowseName of the object instance shall be “Calibrator_<Manufacturer>_<SerialNumber>”.

Example: “Calibrator_battenfeld_0123456”.

6.2 DeviceClass

The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Calibrator”.

6.3 PositionZ, PositionsX, PositionsY

These Objects represent the z-position and the several x- and y-positions of the calibrator. The MeasuringDeviceType and MeasuringDeviceType are defined in OPC 40083.

Definition of directions (from extruder output):

6.4 PositionsPipeSupport

This Object represents the positions of a pipe support. The MeasuringDeviceType is defined in OPC 40083.

6.5 CalibrationZonesType

This Object is a container for the calibration zones but gives also information about the total water flow and water temperature.
